Chapter 8.2, Problem 45MS

What’s the big event? The section defines the probability of the event E as follows. If T equals the total number of equally likely outcomes and N equals the number of these outcomes (all different) in the event E, then the proba bility of the event E equals NIT. For each given probability below, find the number of outcomes N.

${{}^{\frac{N}{T}=\frac{3}{5}\text{ and }T=100;}}^{\frac{N}{T}=\frac{5}{8}\text{ and }T=48;}{}^{\frac{N}{T}=0.40andT=75.}$
